SPINNING APPARATUS.

srncrrzcArron forming part of Letters Patent No. 614,145, dated November15, 1898.

Application filed May 10, 1897. Serial No. 635,886. (No model.)

To all whom it may concern:

Be it known that we,RICHARD TODD, manufacturer, of Heather Bank,Broomfield road, Heaton Chapel, and J EssE AINSWORTH Srorr,

architect and engineer, of 5 Cross street, Man= chester, county ofLancaster, England, subjects of the Queen of Great Britain, haveinvented a new and useful Improvement in Spinning Apparatus, of whichthe following is a full, clear, and exact description.

Our invention relates to improved means for facilitating the spinning ofyarns upon the bare spindle of the ordinary diameter and is applicablechiefly to frames of the throstle type.

The improvements have particular reference to certain furtherdevelopments in and on the method and means already described in UnitedStates patents granted to E. Gessner, Nos. 409,957 and 409,959, and incertain appli cations of our own now pending under Serial Nos. 611,649,611,650, and 611,651. In these specifications is indicated a ferrule orring fitting the spindle loosely, such ferrule carrying a flange or bentfingers which run in a socket or race attached to or formed in theliftingrail. Such ferrule or ring also carries or is provided with afixed or detachable rigid or elastic arm or whip-traveler having an eyeat the upper end through which the yarn passes to the cop on thespindle. To prevent the whip-traveler from flying too far out bycentrifugal force when spinning, a ring or curbing-sleeve supported fromthe lifting-rail or from a further rail is provided. The mode ofspinning by the aid of such loose ferrule, flexible whip-traveler,curbing-sleeve, &c., and the advantages and facilities derived by suchuse are fully disclosed in the specifications and drawings enumeratedabove. YVe find, however, in practice that the perfect working of theferrules, travelers, and sockets is liable to be interfered with by.dustand fluff which is always floating about or present to a greater or lessextent in the atmosphere of the spinning-room. Such fluff, dust, andforeign matter are apt to be drawn in and taken up by the whirl orrevolution of the ferrules and travelers and have a great tendency whenso taken up to clog or choke the parts, thereby causin g friction, whichresults in the sticking and jamming of the ferrule and consequentproduction of bad work. This drawback would tend to militate against thesuccessful commercial working of our frames, so that part of our presentinvention relates to means designed to overcome the disadvantage setforth.

To effect our object, we propose to box in or shroud the space whichexists between the two lifting-rails both at the front and back of therails by means of hinged, pivoted, or sliding doors, so that thesockets, ferrules, and travelers are completely inclosed and shut off.

Our invention also relates to the construction of the curbing-sleeveusually carried by the upper rail, so as to surround the whiptraveler.are liable to become distorted in the process of hardening, and wepropose to produce a composite ring formed from three sections or partsconsisting of a thin outer tube, which need not be hardened, with twohardened and We find that such curbing-sleeves polished rings fixed inthe same, one at the Y lower and the other in the upper part thereof.

Our invention will be more clearly understood on reference to theannexed two sheets of drawings.

On Sheet 1 Figure 1 shows the application of doors to inclose the spacebetween the rails and also the construction of the improvedcurbing-sleeve, just so much of a frame being indicated as will sufficeto illustrate our invention. Fig. 2 is a sectional view at right anglesto Fig. 1, and shows a ferrule fitting the spindle and carrying a whiptraveler. On Sheet 2 Fig. 3 is a plan View, partly in section, ofFig. 1. Fig. 4 shows the application of sliding doors to boxin thecut-out pillar in cases where the curbing-sleeve is carried by such apillar or extension from a single lifting-rail. Fig. 5 is a sectionalplan view of Fig. 4. Fig. 6 shows the application of a tube to surroundthe cut-out pillar.

In the said drawings, F is the lifting-rail, carried by the ordinarypokers f, cut ontin its thickness and fitted with a bush E, and holdingdown ring E, so as to constitute the race for the bent fingers of theferrule D, which supports the whip-traveler C. The upper rail F issupported or carried from the lower rails upon sockets or supports. Asbefore stated, the object of our invention is to box in the spacebetween these two rails, so as to inclose and guard against theadmittance of fluff and dust from the room to the sockets, ferrules, andtravelers. As indicated in the drawings, we provide doors a, adapted toturn down upon hinges b, spaced a suitable distance apart, such doorsbeing held closed by fingers or catches 0, free to turn on pivots 0'.Such doors might be hinged either to the lower or to the upper rail, andalthough we prefer to have a number of such doors along the frame, oneabutting against another, we might have a single door extendingthroughout the length of the rails. It will be ob vious that provisionof such doors enables ready inspection of and access to the parts to behad, so that lubrication is easily effected and a bent or brokentraveler readily replaced. The application of the doors a to the back ofthe rails might be identical with those applied to the front.

Referring to Figs. 4 and 5 and in cases where a single rail is used andthe curbingsleeve supported from a pillar or step E we prefer to shroudor surround the cut-out portions of the pillar by means of sliding doorsa, free to slide in ways formed by clips a, secured to the pillar- E Wehave already set forth the fact that the curbing-sleeve of a continuoustube formation is liable in the process of hardening to becomedistorted, and we now propose to use such a sleeve as is indicated inFigs. 1 and 2. \Ve make this curbing-sleeve in three parts d e f, allcarried by a holder g, adjustably secured to the rail F by means ofscrews and washers g. The thin outer tube 61 need not be hardened; butthe two rings 6 and f are preferably hardened and polished and being ofcomparatively slight depth are not so likely to be afiected in thehardening process. The ring 6 beds in the holder g, and the truth andconcentricity of this ring are a matter of the utmost importance, as thewhiptraveler is almost constantly in contact therewith.

As it is advantageous to be able to readily remove the confining-sleeveG for the purpose of cleaning it, we propose to slit the lower end ofthe thin outer tube dwith two or more slits and to push the same intothe socket or holder g, which might be bored slightly taper, if desired.The tube or shell d carries the ring f at the top, as clearly shown inthe drawings.

In order to lubricate the lower part of the whip-traveler, we prefer tomake a small oilhole d in the tube 01 above the top of the inner ring,as clearly shown in the drawings.

In setting up the parts we adjust and se cure the spindles in thebolster-rail, so as to be absolutely concentric with the socket-race inthe rail F, afterward adjusting the curbing-sleeve G to the spindles,fixing them in their adjusted positions by means of the screws andwashers We claim as our invention In combination in a spinningapparatus, the curbing-sleeve, a ferrule and ferrule-race, alifting-rail carrying the same, and movable means for closing in thespace over and about the ferrule and its race to exclude the dusttherefrom, said means when moved permitting access to the ferrule andits race, substantially as described.

In Witness whereof we have hereunto set our hands in presence of twowitnesses.
